FIELD OF THE INVENTION

The present invention relates to components for medical circuits. In oneparticular aspect, the invention relates to a component locatable aboutthe exterior surface of a corrugated breathing tube, such as for use inthe inspiratory and/or expiratory limb of a breathing circuit, or forcorrugated tubes associated with surgical insufflation systems.

BACKGROUND TO THE INVENTION

In medical applications, such as with assisted breathing, the gasesinhaled by a patient or user are preferably delivered in a conditionhaving humidity near saturation level and at close to body temperature(usually at a temperature between 33° C. and 37° C.). In facilitatingdelivery of gases to a patient in such preferred conditions, breathingtubes (or medical tubes) may be used. Such tubes may take various shapesand configurations. One generally used configuration is (at least) anexternally corrugated tube.

In various instances, the corrugated tubing is advantageously placed orpositioned in certain locations relative to the patient or user. Forexample, the tubing may need to be held in a position or supported suchthat the weight of the tubing such not exert forces on the patient oruser or other associated medical devices they may be using, such asmasks or other interfaces. Enabling the positioning, support andadjustment of tubing between various further positioned or supportedpositions for patients or users would be beneficial.

DETAILED DESCRIPTION OF THE INVENTION

In this specification, the terms “medical circuit” and “breathingcircuit” are used to indicate the general field of the invention. It isto be understood that a “circuit” is intended to include open circuits,which do not form a complete closed circuit. For example, CPAP systemstypically consist of a single inspiratory breathing tube between theblower and the patient interface. The term “breathing circuit” isintended to include such “open circuits”. Similarly, the term “medicalcircuit” is intended to include both breathing circuits and insufflationcircuits, which are also typically “open.” Similarly, the term “medicaltubing” is intended to be read as flexible tubing suitable for use inthe type of medical circuits described above connecting betweencomponents of a medical circuit and providing a low resistance gasespathway between components of a medical circuit.

In the field of medical circuits, and in particular breathing circuits,including anaesthetic circuits, condensation or rain-out can be aparticular problem where high humidity breathing gases come into contactwith the walls of a component at a relatively lower temperature. Withreference to FIG. 14, a humidified ventilation system is shown in whicha patient 100 is receiving humidified and pressurised gases through apatient interface 102 connected to a humidified gases transportationpathway or inspiratory breathing tube 103. It will be appreciated thepatient interface 102 may take the form of a nasal mask, oral mask,oronasal mask, nasal prongs, endotracheal tube or full-face mask, forexample but without limitation.

It should be understood that delivery systems could also be continuous,variable or bi-level positive airway pressure or numerous other forms ofrespiratory therapy. The inspiratory tube 103 is connected to the outlet104 of a humidification chamber 105 which contains a volume of water106. The inspiratory tube 103 may include a heater or heater wires (notshown) which heat the humidified gases within the tube to reduce theformation of condensation. The humidification chamber 105 is heated by aheater plate 107 of humidifier base 108. The humidifier 108 is providedwith an electronic controller which may comprise a microprocessor basedcontroller executing computer software commands stored in associatedmemory.

In response to the user set humidity or temperature value input via dial110, for example, and/or other inputs, the controller determines when(or to what level) to energise heater plate 107 to heat the water 106within the humidification chamber 105. As the volume of water is heated,water vapour begins to fill the chamber above the water's surface and ispassed out of the humidification chamber outlet 104. A flow of gases(for example, air) is provided from a gases supply or ventilator 115,which enters the chamber 105 through inlet 116. Exhaled gases from thepatient's mouth are returned to the ventilator via a return expiratorybreathing tube 130 that may also include a heater or heater wires (notshown), which heat the humidified gases within the expiratory breathingtube to reduce the formation of condensation.

It is preferable that medical tubing (for example the inspiratory and/orexpiratory breathing tubes 103,130) is: resistant to crushing, resistantto restrictions in flow when bent (e.g., increased resistance to flow<50% when bent around a 1 inch cylinder), resistant to kinking,resistant to changes in length/volume under fluctuating internalpressure (e.g., resistance to compliance), resistant to leaking (e.g.,<25 ml/min @6 kPa), have low flow resistance (e.g., increase in pressure@ max. rated flow <0.2 kPa), electrically safe (e.g., resistant tosparks in the tubing) given an operating environment that may beoxygen-rich.

International standard ISO 5367:2000(E) (Fourth edition, 2000 Jun. 1) isone example of how some of these desirable parameters are measured andquantified, and the document is hereby incorporated into thisspecification in its entirety by reference. It is preferable thatcomponents described herein meet or exceed some or all of thesestandards. Further, reference to medical tubes includes breathing tubesas defined in the above ISO standard.

In accordance with certain features, aspects and advantages of thisinvention, a component 1 is provided as an accessory for use withmedical tubing. The components has particular application for thepositioning and support of such medical tubing relative to a user orequipment associated with the user (e.g., user interfaces or patientinterfaces, such as masks, nasal cannula and the like, briefly describedabove).

The ability to locate a medical tube relative to a user has certainadvantages. Being able to help support the weight of the medical tubingconnected to equipment associated with the user has a number ofadvantages including but not limited to, for example, reducing theweight transferred to a user or equipment associated with the user,which may in turn impact on the efficiency of a treatment being providedto a user, or the overall comfort experienced by a user when using suchequipment.

Further, as a user moves or re-positions their body relative to themedical tubing or associated equipment, strain may be transferred to thetubing or to the user via the associated equipment. A relatively quickand effective re-positioning or re-locating of the tubing to providesupport again would be useful. Certain features, aspects and advantagesof the present invention attempt to provide or go at least some waytowards providing at least an alternative component facilitating suchadvantages.

Such a component can be utilised to position or locate inspiratory orexpiratory medical tubing, or other tubing associated with such medicalcircuits as described above. Particular application may have uses in theOSA fields, as well as in hospital situations.

According to the one aspect of the present invention, a component 1 isprovided for use with a tube. The component 1 comprises a body 2engageable with one or more external surface recesses 3 (or surfacerelief portions or sections) of a tube (e.g., such as those of acorrugated tube or tube with a helically recessed surface region). Thecomponent 1 includes a pair of jaws 4 that extend from the body 2. Thejaws 4 can be used for attaching to or for gripping of an item (notshown). In use, in a first orientation 5 of the body 2 relative to thetube recesses 3, the component 1 is movable along a length of the tube.While in a second orientation 6 of the body 2 relative to the tuberecesses 3, the component 1 is resistive to movement along a length ofthe tube.

In a further aspect, the component 1 provides for use with one or moretubes (not shown). The component 1 comprises a body 2 engageable withone or more external surface recesses 3 (or surface relief portions orsections) of respective one or more tubes. The one or more tubes (notshown) are receivable by the body 2, with the body 2 being engageablewith the external recesses of such tubes. The component 1 includes apair of jaws 4 extending from the body 2 for gripping an item (notshown). In use, in a first orientation 5 of the body 2 relative to therespective tube(s) recesses (e.g. corrugations of a tube or tubes), thecomponent 1 is movable along a length of the tube(s), and in a secondorientation 6 of the body relative to the respective tube(s) recesses,the component 1 is resistive to movement along a length of the tube(s).

In respect of the above, it will be seen that FIGS. 1-2 show variousembodiments of a component 1 and in relation to certain tubes of helicalor axial corrugation. The general configuration and arrangement as shownfor the first and second orientations of the embodiments of component 1shown by FIGS. 15-20 will be accordingly understood with reference tothose FIGS. 1-13B.

Advantageously, in the first orientation 5, the component 1 is orientedin a plane such that the body 2 is engageable with certain externalrecesses 3 of the tube when substantially co-axial with the tube. And,in the second orientation 6, the component 1 is oriented in a plane suchthat the body 2 is engageable with certain other external recesses 3 ofthe tube when substantially non co-axial with the tube. It will beappreciated, where for example the body 2 is configured for receivingtwo or more respective tubes, the component 1 is adapted to operate inthe same manner.

Surface recesses 3 can include surface relief features, such asrepeating recesses 3 or other surface relief features such as those of acorrugated tube, or a tube having a helical outer rib extending alongthe length of the tube being held or engaged therewith by body 2.

FIGS. 6A, 7A and 13A show two different embodiments of the component 1in a first orientation 5 relative to a corrugated tube. FIGS. 6A, 6B and13A show a component 1 in a position about a linearly corrugated tube,while FIGS. 7A, 7B and 13B show a component 1 in a position about ahelically corrugated tube. It will be appreciated the component 1 willalso operate in the same manner on a linearly or helically corrugatedtube, or those tubes where the surface recesses 3 or relief features areribs with interposed recesses 3, whether helical or linear relieffeatures or ribs. The component 1 embodiments as shown by FIGS. 15-19operate in the same manner, but are configured with a body 2 adapted toengage with a pair of tubes.

The body 2 substantially surrounds the perimeter, or circumference, ofthe tube(s), such that a portion or portions (such as projection 7 or20, 22 or 30) of the body 2 are engageable with the surface recesses 3or with surface relief portions or sections. Accordingly, the component1 is enabled to be moved along the tube when in a first bodyorientation, yet the component 1 being resistive to being moved alongthe tube when in a second body orientation relative to the tube'srecesses 3 or surface relief features.

As a part of substantially surrounding the tube, an internal surface (orsurfaces or portions of the internal surface) of the body 2 is or areengageable with the one or more external surface recesses 3 (or relieffeatures) of the tube. In this manner, the body 2 may be substantiallyannular about the exterior surface of the tube being engaged. FIGS. 5,11, 12 show such a component 1 in-situ about a tube, and illustrate howportions of the body 2 are engageable with surface recesses 3 or surfacerelief features of the tube to which the component 1 surrounds.

Turning to the jaws 4 of the component 1, in one preferred embodimentthe jaws 4 are configured to be opposing upon one another, or co-actingon each other, when in their closed position 8. Such jaws 4, or othervariations of these, may be configured such that they are hingedlybiased toward each other in reaching a substantially closed position 8.Further, the jaws 4 can be openable from a substantially closed position8 to enable the jaws 4 to receive and then close upon an item forgripping of that item. The jaws 4 can be openable by deflecting the jaws4 away from each other. Manually actuating the jaws 4 to create such adeflection or opening is additionally facilitated by providing fingergrips or tabs for the user of the component 1.

FIG. 3 shows one embodiment of a component 1 where the jaws 4 aredisplaced and yet to be moved into a co-acting or opposing relationshipwith each other, FIG. 4 shows more clearly how the jaws 4 are arrangedwhen the component 1 is provided for use, reference is also made to FIG.2 showing the grips and inter-posing arrangement of the grips on thejaws 4.

In a similar manner, FIGS. 8, 10 and 11 illustrate another component 1embodiment, again where the jaws 4 are yet to be moved into theiropposing relationship. FIG. 12 shows the opposing and inter-posedarrangement of the jaws 4 and grips of such a further embodiment.

The jaws 4 are openable and can receive and then close to grip an itemenabling a more secure option for locating of the tube that is engagedby the component 1.

It will be appreciated this one or more feature, aspect or advantage ofthe invention provides for the re-positioning of the component 1 ontodifferent items or objects, as and where a user desires most useful forcomfort or other reasons.

Further, the component 1 allows the tube (and any attachments connectedwith the tube) to be re-positioned by moving of the tube when thecomponent 1 is moved into the first body orientation that allows thecomponent 1 to be moved along the tube (and about or from surface recessto recess or relief feature to feature) from a first set position to asecond set position. When such a second set position is reached, theuser re-orientates the component 1 such that the second body orientationis achieved to then prevent movement between the tube and component 1(or at least to substantially resist movement between these). FIGS. 6Aand 7A show the first orientation of a component relative to the recessor surface relief features or trough of a tube, while FIGS. 6B and 7Bshow component 1 when in a second orientation 6 relative to a tube'srecesses or surface relief features or trough.

In one form, the portions of the body 2 engageable with the recesses 3(or other surface relief features) are fixed or static portions of thebody 2 (i.e. are not moveable). See for example the annular rib or lipportion 30 of FIGS. 8-13B, or portions 20, 22 of FIGS. 1-7B.

Various items or objects that the component 1 may be attached to (i.e.grip) includes one or more of the following: clothing, bedding,structures associated with personal clothing (e.g. personal lanyard,belt) or bedding (e.g. bed frame, mattress), structures associated withmedical equipment or where a user is located (e.g. stands, bed sidetable), including incubators, and cots. It will be appreciated otheritems or objects can be used to attaching the component 1 to via thegripping jaws 4. Accordingly, when the component 1 is in the secondorientation 6 and the jaws 4 are gripping of an item, the component 1acts to locate the tube in a set position.

In other embodiments, a carer (e.g. mother, father or nurse) may hold achild or infant in a “kangaroo” style hold, and in such an instance thecarer may attach the clip to their clothing such that tubing issupported without placing weight onto the patient interface and on tothe child/infant.

As mentioned above, the body 2 can include a shoulder portion 10 (orfinger tab portion) associated with each jaw of the pair of jaws 4. Sucha shoulder portion 10 assists in providing a surface for actuation, by auser, of the jaws 4 to an open position 9. Such shoulder portion 10 can,for example, be an enlarged region of the body 2.

In use, shoulder portion 10 of the body 2 may be deflectable towardseach other, such that, deflection moves the jaws 4 from a closed orsubstantially closed position 8 toward or to an open position 9. Inreturn, release of the deflection provided by a user allows the hingedlybiased jaws 4 to move back to a closed or substantially closed position8. Advantageously, the shoulder portion 10 can be sized for relativeease of actuation by the fingers of a user, i.e. being finger tabs.

In respect of the jaws 4 of the component 1, one or each jaw can includea grip or grips for gripping (e.g. frictionally) of an item or object.In one form, the grips are one or a series of ridges, projections orteeth 11. Such jaw grips are preferably interlocking or inter-lockable(or interposing) with one or more corresponding grips of an opposing orother jaw.

In another embodiment, one of more of the grips can be shaped so as toexpose one (or a series) of acute angled portions that face inwardlytoward the body. Such acutely shaped portions may assist in helping togrip or grab the textile of a cloth (e.g. clothing or bedding sheets).This may for example be facilitated by the acute angled portionspenetrating or semi-penetrating the weave of the cloth or fabric towhich the grips are attached or becoming embedded into.

In yet a further embodiment, although it should be recognised such afeature may be provided in combination with the acutely shaped portionsdiscussed above, one of more of the grips may be shaped so as to exposeone (or a series of) obtusely angled portions facing outwardly away fromthe body. In such a configuration, advantageously the grips allow theease of insertion of cloth or material into the mouth of the jaws, andtherefore allowing the grips (when released from their open position) toengage with the cloth or material (or object). When provided incombination with the acutely shaped portions, sets of grips may beprovided that allow the relative ease of insertion of material into themouth of the jaws, yet the ability to easily remove the material fromthe grips is reduced by the improved gripping capability of the acutelyshaped portions.

Such a component 1 may be formed of any suitable material allowing theabove described features and deflection characteristics. It may bepreferred that such a component 1 is however provided of a suitable,although not necessarily, medical grade material and, may for example,be of a suitable polymeric material.

In a further form, in the first orientation 5, the internal surface ofthe body 2 may comprise at least one first projection 20 engageable witha corresponding first recess of the tube or of a first respective tube,and at least one second projection 22 engageable with the same oranother recess located near the first recess in which the at least onefirst projection 20 is engageable. And, in the second orientation 6, theinternal surface of the body 2 may comprise at least one first 20 and atleast one second projection(s) 22 that are engaged or engageable with arecess or recesses 3 (or other repeating surface relief features) of thetube, or respective tubes, such recesses separated from one another by adistance along the length of the or each respective tube.

When in the second orientation 6, this further form provides for the atleast one first and at least one second projections 22 to act on thetube, or its recesses 3 or a part thereof (or surface relief features),to restrain (or resist) the component 1 from being moved betweenrecesses 3 (or surface relief features) or along a length of the tube.

As illustrated by FIGS. 1-5, the component 1 comprises two firstprojections 20, and a single second projection 22. FIGS. 5-7B illustratesuch a component 1 engageable with a tube and in the first and secondorientation 6.

As shown by FIG. 6A in the first orientation 5, the two firstprojections 20 are engageable with a corresponding first recess of thetube, and the single second projection 22 is engageable with the same oranother recess located near the first recess in which the at least onefirst projection 20 is engageable (i.e. in an orientation or positionwhen the component 1 is able to be moved along the tube with relativeease).

As shown by FIGS. 6B and 7B in the second orientation 6, the two firstprojections 20 are engageable with a corresponding first recess of thetube, and the single second projection 30 is engageable with a recess ofthe tube separated from the first recesses 21 by a distance along thelength of the tube (i.e. in an orientation or position when thecomponent 1 is resistive to being moved along the tube).

In yet a further form, the component's body 2 can comprise of at leastone lip for engaging with at least one recess of the tube, for exampleas illustrated by FIGS. 8-13B. In such a form, the lip can be one or aseries of projections extending in a substantially annular from andabout a surface of the body 2. Such a lip or lips are those portions ofthe body 2 that are engageable with the one or more external surfacerecesses 3 of the tube, as shown by FIGS. 11, 12. FIG. 13A illustratessuch component when in a first orientation 5, where a second orientation6 of such a component is similar to that as shown by FIG. 13B (but asshown in relation to a helically corrugated tube form). Similarly, thetube may be of axial corrugations (i.e. not helical), and the component1 shown in FIG. 13A may be provided to operate in the manner(orientations) as shown by FIGS. 6A, 7A or when the tube has helicalcorrugations, as shown by FIGS. 7A, 7B.

As shown by FIGS. 15-20, the body 2 is engageable with one or moreexternal surface recesses of respective one or more tubes (multipletubes not shown, but body as shown is configured for receiving a pair oftubes). The body is configured, such that for each respective tube, atleast one first projection 7, 20, 50 is engageable with a correspondingfirst recess of a respective tube. And, the body is also configured,such that for the same tube, at least one second projection 7, 22, 51 isengageable with the same first or another recess, of the same respectivetube.

The component 1 shown by FIGS. 15-20, being of a multi-tube engagingbody form, can be moved to be in the first orientation (e.g. the firstorientation being as shown for example in relation to the single tubecomponent embodiments of FIGS. 1-13B).

In such a first orientation, the internal surface of the body comprises,for each of the respective one or more tubes being engaged by the body,at least one first projection 7, 20, 50 engageable with a correspondingfirst recess of a respective tube, and at least one second projection 7,22, 51 engageable with the same or another recess, of the samerespective tube, located near the first recess in which the at least onefirst projection is engageable. Likewise, a further set of at least onefirst projections 7, 20, 60 and a further set of at least one secondprojection 7, 22, 61 is provided for engaging with a second tube. Itwill be understood that the body 2 may be adapted or shaped to receiveand engage with one, two or more than two tubes.
